System and method for factory work logging

Abstract

Provided is an information processing system which has a plurality of tags, a tag reader, a digital-pen, and a server. The plurality of tags each hold a tag identifier. The tag reader reads the tag identifier held in each of the plurality of tags. The digital-pen reads location information, which identifies a location where handwriting is made on paper. The server keeps work record including information that associates the tag identifier recorded in the server in advance with the location on paper. When it is judged that the read tag identifier and a handwriting location identified by the location information are associated with each other, the server judges whether or not the read tag identifier matches the tag identifier recorded in advance that is associated by the work record with the handwriting location identified by the location information. The server outputs a result of the judging.

Description

CLAIM OF PRIORITY[0001]The present application claims priority from Japanese application JP2008-060787 filed on Mar. 11, 2008, the content of which is hereby incorporated by reference into this application.BACKGROUND OF THE INVENTION[0002]This invention relates to a handwritten information processing system and a handwritten information processing method with which a pattern written by hand onto a paper document is reflected on an electronic document. More particularly, a technology disclosed herein relates to an information processing system which uses a handwritten information processing system and an RFID (Radio Frequency Identification) in combination to create and maintain a work log.[0003]For processes of plant construction, railroad car manufacture, and the like, improving the efficiency of cable wiring work and reducing mistakes in work operations are issues to be tackled. The reliability of those spot works has conventionally been secured by keeping a work log with the use ...

AI Technical Summary

Benefits of technology

[0007]The above-mentioned method developed to improve the work efficiency requires a work site to have sophisticated information technology equipments, including a portable terminal which enables a worker to refer to design information and a control system for controlling LEDs attached to the wiring board from the worker's portable terminal or from a server. Using those many information processing equipments on a work site increases the maintenance cost and provokes more frequent work delays caused by failures in the information processing equipments, with the result that the work efficiency is not improved much.

[0009]It is therefore an object of this invention to provide a means to solve the above-mentioned problems through an accurate record of work operations which is obtained without using many sophisticated information processing equipments on a work site and without increasing the burden on workers.

[0011]According to an embodiment of this invention, the reliability of handwritten work log information can be improved. This invention also makes it easy to find mistakes in work operations and miswriting.

Problems solved by technology

In the conventional logging method using a paper checklist where a worker writes in the checklist by hand, it is practically impossible to eliminate miswriting completely and the accuracy of records is not satisfactory.

Other problems of the logging method using a paper checklist stem from recording information on paper, including difficulties in sharing information and vulnerability to falsification.

Systems using a digital-pen, too, are having only a limited success in securing the reliability of information, for the act of writing itself carried out by hand.

Using those many information processing equipments on a work site increases the maintenance cost and provokes more frequent work delays caused by failures in the information processing equipments, with the result that the work efficiency is not improved much.

Further, in manual work with diverse features such as construction work, it is sometimes impossible or inappropriate to strictly follow the specifications of the blueprint, depending on how things are going on the work site.

The above-mentioned method which guides work according to design information is often inadequate for those applications.
